Figure 2 - 20. Management, Signaling and Media Port Assignments

Without powering down the Acme Packet 4500, you can exchange an NIU (for the same type of card) by removing and replacing it. Upon NIU removal, the Acme Packet 4500 enters an Out-of-Service state. After you reinsert the NIU and connect to the ACLI, you must reboot the system to return to service. This causes a soft-reboot rather than a system power cycle.

Console Port The console port on the NIU provides console access to the Acme Packet 4500 over a RS-232C serial connection. The Acme Packet 4500 supports only one active serial console connection at a time. The rear console port is useful for customers who want permanent console access; the front console port provides easy access to the Acme Packet 4500 for a temporary connection.

Console port communication is used for administration and maintenance purposes from a central office (CO) location. Tasks conducted over a console port include:

• Creating the initial connection to the Acme Packet 4500

• Accessing and using all functionality available via the ACLI

• Performing in-lab system maintenance

Console Port Pin-out Acme Packet 4500 console ports are accessed through one of the two RJ45 jacks on the system console. Because the Acme Packet 4500 does not employ any type of flow control on its RS-232 ports, only the RX, TX, and GND pins are used. The following table identifies the pin assignments and signal names/descriptions for the console connector.

Figure 2 - 21. Console Adapter

Alarm Port The alarm port on the NIU is a flexible interface that closes a circuit when a specific alarm level becomes active on the Acme Packet 4500. The Acme Packet 4500 features an alarm control signal interface that can be used in a CO location to indicate when internal alarms are generated. The Acme Packet 4500 uses alarm levels that correspond to three levels of service-disrupting incidents. When any of the three alarm levels is generated, the corresponding circuit for that level on the alarm port is closed.

Alarm Levels The following table lists the three alarm levels:

Table 2 - 2. Alarm Severity Levels

Alarm Type Description

Minor Functionality has been impaired to a small degree (e.g., a single fan has failed).

Major Pending failures or unexpected events (e.g., a loss of signal).

COMPONENT OVERVIEW

the physical and network interface configuration elements. Refer to the System Configuration chapter of the Acme Packet Configuration Guide for details.

Once the management network interface is configured, it should be reserved for the following:

• Maintenance activities

• Application log retrieval

• Software upgrades

• System configuration

• Telnet, SSH, SNMP, FTP, and SFTP connections

• RADIUS CDR transmission

It is recommended that you use shielded CAT5e or CAT6 Ethernet cables with RJ45 plugs for connecting to the rear-panel Acme Packet 4500 Ethernet interfaces. These Ethernet interfaces have a distance limitation of 328 feet (100 m), as defined by the FAST Ethernet standard, IEEE 802.3.

Signaling and Media Interfaces

The signaling and media interfaces provide network connectivity for signaling and media traffic. Each interface can connect to a network at GbE speeds. Network interface and hardware options differentiate the available NIU cards for order.

NIUs are available in the following configurations:

• 4-port 10/100/1000Mbps Copper (RJ45)

• 4-port GbE SFP (LX, SX, or Copper) [1000Mbps for SX, LX; 10/100/1000Mbps CX]

• 4-port GbE SFP with QoS and IPsec (LX, SX, or Copper)

• 4-port GbE SFP with IPsec (LX, SX, or Copper)

The optical GbE cards can accept an LC fiber connector using either single mode or multimode cable.

Mixed transceiver types are unsupported on SFP-based NIUs; all 4 ports are required to be populated with identical SFPs, based on compliance testing.

Power Components

The Acme Packet 4500 offers AC or DC power options for the Acme Packet 4500. The power supplies are user-replaceable, hot swappable components.

COMPONENT OVERVIEW


Power supplies are accessed from the rear panel of the system chassis. The right power supply is designated as power supply A, and the left power supply is designated as power supply B.

Power Supply B Power Supply A

Figure 2 - 24. Power Supply Designations

Power Supply Redundancy

During normal operation, the Acme Packet 4500 is load-balanced and draws power from both supplies. The two power supplies also provide hardware redundancy. If a power supply fails, the Acme Packet 4500 can rely on only one functional power supply to sustain normal operation. A malfunctioning power supply must be removed and replaced as soon as possible. If the Acme Packet 4500 starts up with only one power supply, it will not generate an alarm.

AC Power The auto-sensing AC power supply is rated at 110-240 VAC, 50-60 Hz, and comes with an IEC connector. You insert and remove the power supply from the system chassis by its handle. Use the locking screw to lock the power supply into the chassis.

IEC Connector Handle Locking Screw

Figure 2 - 25. AC Power Supply Interface Components

AC Power Cords Acme Packet ships all AC-powered Acme Packet 4500s with one 2 meter, 3-conductor 18 AWG power cord for each power supply. The power cord connects to the IEC-320 receptacle on the power supply.

DC Power Acme Packet ships all DC-powered Acme Packet 4500s with one 8’ power cable with each power supply. The Acme Packet 4500 can be powered by central office –48 VDC operations with a DC-DC supply. You insert and remove the power supply from the

Power Supply Switch

Power switches are located on the system’s power supplies and face rearward from the Acme Packet 4500. The Acme Packet 4500 has no other power switches. For normal operation, the switches on each power supply should be in the ON position. Flipping both switches to the OFF position immediately powers down the Acme Packet 4500. The side of the switch labeled with a 1 is on and 0 side is off.

Caution Both power switches should remain in the ON position at all times. Do not touch a power supply switch unless specifically instructed to do so by your Acme Packet customer support representative.

COMPONENT OVERVIEW


Grounding Terminals The grounding terminals are used to attach the Acme Packet 4500 chassis to a local earth ground. The terminals are located between the two power supplies on the chassis rear.

Cooling Components

The Acme Packet 4500 must remain well ventilated for reliable and continuous operation. The cooling features of the chassis include:

• Fan module

• Fan Filter

Fan Module The Acme Packet 4500 chassis pulls cool ambient air into its chassis through intake fans and is exhausted through perforated air outlets located along the rear of the chassis. To avoid overheating the system, do not block the air intake or exhaust ways or otherwise obstruct airflow to the system in any way.

The following figure shows the Acme Packet 4500’s fan module. The fan module attaches to the chassis with two captive screws, and is powered by a connector that joins to the motherboard when screwed into the chassis. The air filter is not shown in this image.

Figure 2 - 27. Fan Module

The Acme Packet 4500 automatically adjusts fan speed based on the current operational status and environmental conditions. Fan speed regulation is an automated process that requires no user intervention. You can monitor the status of the fan speed from the Environment menu of the graphic display.

The fan module is a user-replaceable, hot-swappable component. If the Acme Packet 4500 experiences a fan module malfunction and generates an alarm, you must remove the existing fan module and replace it with a fully functioning fan module.

Air Filter The Acme Packet 4500’s foam air filter removes airborne particles before they are drawn into the system chassis.


COMPONENT OVERVIEW

Acme Packet4000 Series Hardware Architecture

The hardware architecture of the Acme Packet4000 series hardware architecture is depicted below. The Acme Packet4000 series hardware is purpose built for SBC applications and relies on state-of-the-art network processing and traffic management components to deliver the necessary platform for delivering security and scalable media processing.

The Network Processing (nP) subsystem is comprised of the network processors, traffic management, and content addressable memory (CAM). This subsystem hosts the media control module and is completely hardware based. Adjunct to the network processing components are the QoS engine for monitoring bearer QoS metrics.

The signaling processor subsystem is comprised of the host subsystem and associated memory (noted in red in the diagram). The session control functions including the session signaling layer, call routing and management elements are hosted on the signaling processor subsystem.

The separation of signaling and media processing is absolutely necessary for the following reasons:

• Guarantee media processing will never overwhelm signaling processing. Signaling processing performance is not impacted by media processing load as it is with single more monolithic solutions based on general purpose computing platforms.

• Protection of the signaling processing subsystem for overload and DoS attacks. When DoS attacks are detected, these attacks are policed and isolated in hardware.

The following architectural diagram is a logical representation of the Acme Packet 4500. The Acme Packet 4500’s Network Processor is physically one device.

Figure 2 - 28. Acme Packet 4500 Hardware Architecture

Media Cabling for HA Nodes

NIU media port cabling in an HA node depends on network topology. After a switchover between the two Acme Packet 4500s in an HA node, the standby system sends out an ARP message using a configured virtual MAC address, establishing that MAC on another physical port on the same Ethernet switch.


5 Startup

Introduction

This chapter describes Acme Packet 4500 startup which involves two tasks:

• Powering on the Acme Packet 4500.

• Creating the first console connection to the Acme Packet 4500.

You can perform these actions in any order. However, if your console connection is configured first, you can observe the booting processes as your Acme Packet 4500 goes online.

The last section of this chapter explains how to log in to your system.

6 Maintenance

Introduction

This chapter explains Acme Packet 4500 hardware maintenance procedures. This chapter also provides hardware alarm information.

System Shut Down

Although several user-replaceable components of the Acme Packet 4500 are hot-swappable, some Acme Packet 4500 maintenance procedures require that you shut down the system.

Before you shut down or restart the Acme Packet 4500, ensure that there are no active calls in progress. Procedures to reroute call and network traffic around the Acme Packet 4500 are outside the scope of this guide.

You can set the Acme Packet 4500 to reject all incoming calls from your system with the set-system-state command. When set to offline, this command lets calls in progress continue uninterrupted, but no new calls are admitted.

After all call processing has stopped, you can power off your Acme Packet 4500. Shutting down the system is appropriate when you are replacing a physical interface card, power supply, or are removing the Acme Packet 4500 from the equipment rack.

Rejecting Incoming Calls

To reject all incoming calls on the Acme Packet 4500:

1. In Superuser mode, type set-system-state offline and press <Enter>.

ACMEPACKET# set-system-state offline

Setting system state to going-offline, process will complete when all current calls have completed

ACMEPACKET#

After all call processing has stopped, you must halt the operating system before you power off your Acme Packet 4500 when running S-CZ software images. Shutting down the system is appropriate when you are replacing a physical interface card, storage device, power supply, or are removing the Acme Packet 6300 from the equipment rack.

Shutting down the Acme Packet 4500

1. In superuser mode, type halt and then press <Enter>, then answer y followed by <Enter> at the halt confirmation prompt.

ACMEPACKET# halt

To shut down the Acme Packet 4500 hardware:

1. Exit the ACLI and close your console or network connection.

2. Turn off the power supply switches on the rear panel of the Acme Packet 4500 by pressing the 0 side of the switch.

Figure 6 - 93. Power Supply Switches (highlighted in red)

Confirm that the graphic display is dark and all fans are off. You can now unplug the Acme Packet 4500 from its power supply and continue with maintenance procedures.

Rebooting, Resetting, and Power Cycling

Reboot Rebooting the Acme Packet 4500 shuts down the system in an orderly fashion and then starts it up again. The operating system gracefully shuts down as processes are terminated and the file system is stopped. While the system and its processes are stopped, all call processing is immediately halted. You may therefore wish to perform tasks that call for a reboot during off-peak maintenance hours.

Rebooting the Acme Packet 4500 is required every time you upgrade with a new version of the Acme Packet 4500 software.

Before rebooting the Acme Packet 4500, save your configurations. Refer to the Maintenance and Troubleshooting Guide for a full explanation of this procedure. The save-config command is used to save the configuration in the example below.

For a full explanation and all options for the reboot command used in the example below, refer to the ACLI Reference Guide.

To reboot the Acme Packet 4500:

1. Save any configuration changes you have made in the ACLI by typing save-config <Enter> in Superuser mode.

ACMEPACKET# save-config

WARNING: you are about to reboot this SD!

-----------------------------------------

3. Type Y and then press <Enter> at the confirmation prompt to proceed with the reboot.

Reboot this SD [y/n]?: y

System Reset Resetting the Acme Packet 4500 via the front of the chassis performs a cold reboot. This is the equivalent to disconnecting the power from the system and then reconnecting it. There is no orderly termination of tasks, and the system shuts down abruptly. You should only reset the Acme Packet 4500 when it becomes unstable and no other means of gaining administrative control is possible.

During a system reset, certain files are not closed properly, and they may become corrupted. Depending on what files become damaged, the system might become completely unusable.

Caution Always try to first reboot the Acme Packet 4500 from the ACLI before performing a cold reset. Only reset the system as a last resort.

To reset the Acme Packet 4500:

1. Insert a rigid paperclip-sized tool into the small hole on the front of the chassis beneath the graphic display.

Figure 6 - 94. Reset Button

The system immediately resets and begins its initialization and boot sequence.

Power Cycling Power Cycling the Acme Packet 4500 is the process of turning the chassis off then on from the switches on the power supplies or by equivalent means to remove power


MAINTENANCE

from the system. It is imperative that you wait at least 10 seconds between power down and power up to ensure that all components are completely powered down before restart.

Power cycling the Acme Packet 4500 without performing a halt operation can lead to data loss to the Storage Device when running S-CZ software images. To ensure stable operation a file system check will be performed on the next power up. This check may take several minutes to complete, and should not be interrupted.

Standby Mode for HA Nodes

When performing hardware maintenance on the Acme Packet 4500, it is best to minimize any risk of interrupting network traffic or losing data. If the Acme Packet 4500s are configured as an HA node, you should only work on the Acme Packet 4500 that is in standby mode.

There are two ways to determine the HA state of each Acme Packet 4500 in an HA pair.

1. If you are in the same physical location as the Acme Packet 4500s, you can view the graphic display on the front panel. The display will indicate HA state as explained in the Graphic Display Output for HA Nodes section of the Graphic Display chapter of this guide. There is no (S) designation for an active system, but there is for a standby system.

2. If you are not in the same physical location as the Acme Packet 4500s, you can use the ACLI show health command. The output of this command indicates the current HA state of the Acme Packet 4500.

Once you have determined that the Acme Packet 4500 due for maintenance is in standby mode, you can continue with the appropriate procedures to replace a part.

If you need to perform maintenance on the active Acme Packet 4500, you need to manually force the two Acme Packet 4500s to switch HA states. Forcing a switchover renders the currently active Acme Packet 4500 standby, and the currently standby Acme Packet 4500 will assume all traffic processing and forwarding as the active system.

Caution This procedure is only applicable to Acme Packet 4500s in an HA deployment.

MAINTENANCE


To force a Acme Packet 4500 into the standby HA state:

1. Confirm that the relevant systems on SBC1 and SBC2 are synchronized with the show health command. Type show health and press <Enter> on each system. NETNETSBC1# show health

MAINTENANCE

Power Supply Removal and Replacement

This section explains how to remove and replace the power supplies in the Acme Packet 4500 chassis.

Caution When removing or replacing a single power supply in a running chassis, ensure that its power switch is turned off first. Failure to turn off the power supply switch before insertion or removal may damage the system. After physically switching off a power supply, disconnect it from the power source before you remove or install it in the chassis.

Caution Both power supplies must be the same type AC or DC. The power supplies must be populated with two identical power supplies made by the same vendor. The vendor is identified by the label on top of the power supply.

The power supply is a user-replaceable component. If a Acme Packet 4500 power supply malfunctions, you should remove the malfunctioning power supply and replace it. The power supply can be removed from the chassis while still installed in the rack and while the second power supply is providing system power; this is called a warm swap. When removing and replacing a power supply, remember to first ground yourself using appropriate ESD grounding equipment such as a wrist or heel strap.

Note: See Power Components for an explanation about power supply numbering.

For information regarding how to obtain a replacement power supply, contact your Acme Packet customer support representative directly or E-mail [email protected].

AC or DC Power Supply Removal

You can remove AC and DC power supplies with the same procedure once they are disconnected from their power source. The images used in the procedure below use an AC power supply.

Note: You can have the system up and running during this procedure if you are changing out a defective power supply.

1. The system is up and running.

2. Locate the defective power supply.

3. Turn the power switch to the OFF position on the defective power supply only.

4. Follow the procedure below.

MAINTENANCE


To remove a power supply from the Acme Packet 4500 chassis:

1. Remove the AC or DC power cables (see: Ground and Power Cable Installation) from the power supplies.

2. Turn the locking screw fully counterclockwise to unlock the power supply from the chassis. This may require 4-6 full turns.

Figure 6 - 97. Unlocking the Locking Screw

3. Hold the removal handle and gently pull the power supply out of the power supply bay.

Figure 6 - 98. Removing the Power Supply

4. Continue to pull the power supply all the way out of the chassis until you have completely removed it.

Figure 6 - 99. Power Supply Removed

AC or DC Power Supply Replacement

You can replace AC and DC power supplies in the Acme Packet 4500 chassis by reversing the procedure to remove them. You can also install power supplies in the Acme Packet 4500 chassis before or after the chassis is mounted in an equipment rack. The images used in this section use an AC power supply for demonstration.

Caution NEVER power up a power supply before it is installed in the Acme Packet 4500 chassis.


MAINTENANCE

You can first perform the DC Power Cord Installation procedure prior to installing a DC power supply as extra leverage and space will be helpful for performing this task. If this ordering is used, DO NOT connect the supply end of the power cord to the power source before the power supply is installed in the Acme Packet 4500 chassis.

Ground yourself with an ESD wrist strap before installing a power supply.

To install a power supply in the Acme Packet 4500 chassis:

1. Locate the power supply.

2. Locate the empty power supply bay in the chassis.

Fan Module and Filter Maintenance

This section explains how to remove and replace the fan module and air filter on your Acme Packet 4500.

Removing and Replacing the Fan Module

The fan module is a user-serviceable, hot-swappable component. If the Acme Packet 4500 experiences a fan module malfunction, you must remove the existing fan module and replace it with a functional one.

The hot-swappable fan module removal and replacement procedures require that you have a replacement fan module on hand. In order to maintain system operations, you must be able to remove the malfunctioning fan module and quickly replace it with a functioning one to prevent the system from overheating.


MAINTENANCE

Caution An over-temperature condition can stop packet processing.

If you do not have a replacement fan module nearby, always shut down the system and disconnect the power before removing the malfunctioning fan module to replace at a later time.

When removing and replacing a fan module, remember to first ground yourself using appropriate ESD grounding equipment such as a wrist or heel strap.

To remove the fan module:

1. Press two fingers against the left end of the plastic fan bezel and pull directly toward you. The fan bezel comes off of the chassis. Set the fan bezel aside.

Figure 6 - 104. Removing the Front Bezel

2. Pinch the black foam air filter at one of its corners and pull it directly away from the chassis. You will see the fan module.

Figure 6 - 105. Removing Air Filter from Chassis

3. Unscrew the two captive screws at each end of the fan module using a #2 Phillips screwdriver.

Figure 6 - 113. Re-Installing the Fan Bezel

Maintaining the Cooling Components

The Acme Packet 4500 air filter removes airborne particles before they are drawn into the Acme Packet 4500 chassis. To prevent system malfunction and prolong the life of the system cooling components, follow these guidelines:

• Clean or replace the air filter every three months.

• Clean the air inlets once a week.

Cooling maintenance encompasses cleaning the fan module and cleaning the air inlets on the front of the Acme Packet 4500 chassis. Cleaning the fan module requires that you remove the module itself. If you are not shutting down the Acme Packet 4500, this procedure must be performed quickly; otherwise, the system may overheat and cause packet processing to stop.

This maintenance should be performed alongside other preventative maintenance to take place within a planned maintenance or downtime window, during off-peak hours.

MAINTENANCE


Cleaning the Cooling Components

To clean the fan module:

1. Refer to the instructions detailed in the section Removing and Replacing the Fan Module in this chapter to remove the fan module from the chassis.

2. Spray compressed air into the fan module to dislodge and blow away any contaminants and clean out the four fans.

3. Refer to the instruction detailed in the section Removing and Replacing the Fan Module in this chapter to replace the fan module.

To clean the perforated air inlets:

1. Remove the fan bezel from the chassis.

2. Gently wipe the front fan bezel that contains the perforated air inlets with a clean, dry cloth. You can alternatively remove the fan bezel from the system and use compressed air to clean out the perforated air inlets.

Note: Only the removable fan bezel has vent holes that require cleaning.

Caution To prevent damage to the painted finish, do not use any solvents or liquids to clean the perforated air inlets on the front of the chassis.

NIU Removal and Replacement

When possible, remove system power before removing and replacing an NIU. However, without powering down the Acme Packet 4500, you can exchange an NIU (for the same type of card) by removing and replacing it. Upon NIU removal, the Acme Packet 4500 enters an Out-of-Service state. After you reinsert the NIU and connect to the ACLI, you must reboot the system to return to service. This causes a soft-reboot rather than a system power cycle.

Caution Make sure you are properly grounded with an ESD strap before removing the NIU.

NIU Removal To remove an NIU:

1. Unplug all network and management cables from the NIU you plan to remove from the Acme Packet 4500 chassis.

Note: This will cause a link loss on all connections.


MAINTENANCE

2. Unscrew the two thumbscrews located on each side of the NIU with a #2 Phillips screwdriver. The screws are spring-loaded and will push forward, but they will not fall out of the NIU.

Figure 6 - 114. Loosening Thumbscrews

3. Pivot the two ejection levers outward at the same time, pulling the card out of its connection to the motherboard and away from the system chassis. This action disengages the NIU from the system, severing all electrical contact to the processing unit.

Figure 6 - 115. Pivoting Ejection Levers Outward

MAINTENANCE


4. Pull the loosened NIU out of the Acme Packet 4500 chassis by holding each side of the NIU front panel.

Figure 6 - 116. Removing the NIU

5. Place the NIU in an antistatic bag while it remains outside of the Acme Packet 4500 chassis.

NIU Replacement To install an NIU in the Acme Packet 4500 chassis:

1. Locate the NIU.

2. Ensure that the ejection levers on the front of the card are in the open and extended position.

Figure 6 - 117. Ejection Levers in Open and Extended Position

3. Hold the NIU by its sides with the front panel bezel facing you.


MAINTENANCE

4. Note the two flared guide rails that the NIU rides as it is inserted into the Acme Packet 4500 chassis. The guide rails guide the interface unit to engage the NIU bus connector squarely.

Figure 6 - 118. Guide Rails

5. Slide the card into the Acme Packet 4500 chassis. The physical interface card circuit board slides into the guide rails in the NIU bay of the system chassis.

Figure 6 - 119. Re-Installing the NIU

MAINTENANCE


6. Continue sliding the card into the chassis until the ejection levers catch the chassis. At this point, the ejection levers will start to fold inward as the NIU is inserted into the chassis.

Figure 6 - 120. Installing the NIU

7. Fold both ejection levers inward toward the card to complete the connection to the motherboard. Pushing the ejection levers inward draws the physical interface card toward the system chassis and completes the connection.

Figure 6 - 121. Securing Connection of NIU to Chassis


MAINTENANCE

8. Screw the NIU into the chassis with a #2 Phillips screwdriver. This creates the final connection between the interface unit and the chassis.

Figure 6 - 122. Tightening Thumbscrews

9. Replace all network and management cabling.

Optical Transceiver Removal and Replacement

Your troubleshooting and diagnostics might reveal that the optical transceiver component of a GbE optical physical interface card needs to be replaced. The optical transceiver serves two functions:

• Converts electrical signals into optical signals used to communicate with other optical networking equipment.

• Serves as the receptacle for the LC duplex fiber optic connectors.

Optical transceivers are hot swappable and may be replaced while the Acme Packet 4500 is powered on. Leave the NIU in the Acme Packet 4500 as you extract the optical transceiver.
